DUIVIPING-WAGON.

SPECIFICATION forming part of Letters Patent No. 642,395, dated January30, 1900.

Application filed J'uly 7,1899. Serial No. 723,026. (No model.)

To @ZZ whom t may concern:

Be it known that I, DAVID S. 1WATSON, of Canastota, in the county ofMadison, in the State of New York, have invented new and usefulImprovements in Dumping-XVagons, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to dumping-wagons of the general class or typeshown in the Letters Patent granted to me February 21, 1888, No.378,272.

My objectis to improve upon the construction there shown, myimprovements being also adapted to be used upon wagons of differentconstruction. They relate specifically to ratchet-and-pawl mechanismsfor dumping or closing the bottom of the box and applying a brake to theratchet, whereby the dropping of the bottom will be retarded more orless and at least sufficiently to prevent all the liability to damageincident to a free drop, comprising a spring-pawl operating normally toengage with the ratchet to carry the load and having a head mountedthereon by a knuckle-joint, one end of which is the point of thepawl,and means to shift the pawl-body out of center with said head, wherebythe weight of the load will swing said head and bring its flat face intocontact with the face of the ratchet, so that Vit will operate as abrake to retard the backward rotation of the ratchet which permits theunwinding of the bottom-closing chain. They also relate to devices forregulating the distance of the openingof the bottom sections, wherebythe load can be dumped in a heap or can be distributed over a greaterdistance. It is constructed as follows, reference being had tov from thedriving or winding-up pawl. Fig. 6 is a like view of the same, showingthe ratchet controlled only by the brake action of the pawl-head.

The drawings illustrate my improved devices applied to the wagon shownand described in my patent aforesaid, and for that reason I will onlydescribe the parts which relate or belong to my improvements.

vA is the ratchet upon the outer end of the winding-shaft, which issuitably j ournaled in the box. A ratchet-lever 2 is suitably mounted sothat by pressure upon the hand lever or grip 3 the pawl 4 will engagesaid ratchet to revolve it and the winding-shaft to wind up the chainsand close the sections of the bottom 5 of the box in the usual manner.Upon the side of the box a block 6 is secured, to which is pivoted thebody 7 of the load-supporting pawl provided with ashoulder 8, and 9 is aspring suitably mounted and engaging with said pawl-body. A head 10 ismounted with a knuckle or other suitable joint upon or in the free endof said pawl-body, said head having al point to suitably engage with Ythe ratchet-teeth and a dat face to engage atwise with the ratchet whentripped to operate as a brake spring-pressed to retard the backwardrotation of the ratchet, retard the unwinding of the chains and thedropping of the bottom, and relieve the hinges and chains from liabilityto damage especially with a heavy load. As a means for tripping thiscombination pawl and brake a lever 11 is pivoted upon the lever 2 andconnected by a rod 12 to a hand-grip 13, whereby the free end of thetrip-lever is swung into position and by swinging said lever 2 isbrought against the pawl-body and the free end thereof swung down untilthe strain against the point of the head will swing said head intoposition to operate as a brake.

Hooks or eyes Mare secured upon the bottom sections, usually an eye onone and a hook upon the other, and 15 is a chain mounted thereon andadjustable as to length, as by shifting the hook Yfrom one link toanother, whereby, as shown in Fig.y3, the bottom sections will only openthe distance pery the point of engagement of the pawl out of,

intted by the bight of the chain and whereby the load will bedistributed according to the width of the space.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination with a winding-ratchet of a pawlcomposed of abodypivotally mount ed, a head, having a point and a flat face, pivoted uponsaid body, a spring engaging with said body, and a lever adapted toengage therewith and swing said body in one direction, while the strainupon the ratchet will tilt said head in the opposite direction.

2. The combination with a winding-ratchet of a pawl composed of sectionshinged together, and having a shoulder on one section, a spring engagingwith one section to hold alinement with the pivot connecting thesections and the pivot of the pawl, a lever engaging with said shoulderto swing that seotion whereby the strain on the ratchet will swing theother section and bring its flat face into engagement with the face ofthe ratchet.

3. The combination withawinding-ratchet, of a pawl composed of a bodyand a head hinged thereon having a flat face and a pawlpoint wherebywhen said ratchet is revolved in one direction it will operate as apawl, and when in the opposite direction said head will swing and bringits vdat face against said ratchet as a brake, and means to retain saidpawl in either position. l

In witness whereof I have hereunto set my hand this 4th day of July,1899.
